TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES I. WILSON, of Elmwood, in the county of Peoria, and State of Illinois, have invented a new and valuable Improvement in Means for Destroying Bugs upon Growing PotatorPlants; and do hereby declarethat the following is a full, clear, and exact description of the construction and operation of the same.

The nature of my invention consists in providing a chemical compound, in the form of a powder, to he sown upon the potato-plants, which said powder shall produce death to-the insect called the potato-bug.

"My chemical powder is formed in the following manner:

I take one part of Paris green, and two parts of mineral paint, of any manufacture, and mix them thoroughly together until they are merged into one common powder; r

v The object of mixing the paint with the Paris green is to so dilute or unite the latter therewith that no injury shall result to the plants.

I I-take the powder thus prepared, and sow a small quantity thereof upon the growing potato-vines. The best time for sowing it upon the vines is early in the morning, whilethere is dew upon-the vines.

This powder acts as a deadly poison to potato-hugs, and a very few applications thereof will serve to protect the potato-crop from that pernicious and destructive insect.

What I claim as my invention, and desire to secure by Letters Patent, is I A powder, prepared of the materials and in the manner specified, to be used for the destruction of potato-bugs. Y

In testimony that I claim the above, I have hereunto sifbscribed my name in the presence of'two witnesses.

JAMES P. WILSON.
